New Standard in Arm Support

Kinetic Arm is the first dynamic arm support system engineered to stabilize both the shoulder and elbow simultaneously during high-demand arm movement. Designed for repetitive and high-stress actions such as throwing, swinging, serving, and rotational motion, it delivers coordinated, dual-joint support that traditional compression sleeves, kinesiology tape, and arm braces cannot provide.

Powered by multi-patented MuscleWeb® technology and constructed with medical-grade materials, Kinetic Arm provides motion-responsive, directional stabilization that activates during vulnerable phases of movement. Independent, published biomechanics research demonstrates how this dynamic support helps reduce mechanical arm stress and manage load across both joints—without restricting natural range of motion, power, or velocity.

Trusted by athletes, active individuals, and professionals whose activities place repeated demands on the arm, Kinetic Arm supports consistent mechanics, helps manage fatigue, and promotes confident performance during repetitive, high-intensity arm use.

Beyond Compression. Beyond Bracing.

Traditional arm sleeves rely on uniform compression, while rigid braces create support by limiting movement. Neither approach adapts to how the arm actually functions during dynamic activity, nor do they address the coordinated demands placed on both the shoulder and elbow during repetitive motion.

Kinetic Arm is engineered differently. This dynamic arm stabilization system provides adaptive, multi-directional support to both the shoulder and elbow—designed to engage during the most demanding phases of movement and reinforce the arm when it needs support most, without limiting natural range of motion, power, or speed.

Worn during training, competition, and active recovery, Kinetic Arm supports confident movement and helps manage the strain associated with repetitive arm use, promoting more efficient movement patterns over time.

IMPRESSIVE TECHNOLOGY

MuscleWeb® DESIGN

MuscleWeb® technology combines a precision bio-knit weave with HD-bonded, flexible polymers—constructed with medical-grade materials—to create dynamic, dual-joint support for the shoulder and elbow. This movement-responsive structure activates under load to help manage mechanical forces and support efficient arm mechanics without limiting natural motion.

HOW IT WORKS
Validated by Research
TESTED & PROVEN

Kinetic Arm isn't just innovative—it's scientifically proven.

Through 10+ years of biomechanics research using 3D motion-capture and IMU sensor technology, Kinetic Arm has demonstrated:

✓ Significant reduction in elbow varus torque
✓ Expedited return to sport during rehabilitation
✓ Maintained natural velocity and mechanics

"As an orthopedic physical therapist, I really like this product for not only recovery from elbow and shoulder injuries, but also in helping to reduce said injuries in the first place. I have suggested this to numerous baseball and volleyball players who love its results! Fantastic product and I’m glad you guys took the time to think about how to make something like this because it’s definitely making a difference."

" I have now used it with a variety of my athletes in physical therapy and have seen it reduce pain with throwing from a 7/10 to a 0/10 by just simply putting it on. The Kinetic Arm’s ability to offload stress while allowing proper mechanics and full ROM, the process can be streamlined with better outcomes. Highly recommend 10/10!"
